Back in Coop's room, Coop waits worriedly from outside the cat house as Kat works on the device. Just then, he hears from the TV downstairs, "We interrupt this broadcast of professional monkey wrestling with a special news bulletin." Curious, he hurries downstairs, and soon has his suspicions on this matter confirmed when an image of Dennis roaming the edge of a volcano. "This report comes from Hawaii, where a young local has gotten lost hiking...VERY lost!" the announcer elaborates. From on the screen, Dennis pauses for a moment and waves to the camera.

"Say," Burt, who's watching this from the couch, notes. "That looks a lot like Dennis!"

"Uhm, please don't be concerned, Dad," Coop quickly amends, as he traipses up to his father. "I'm sure it's just a traveler who looks like him."

"Mmn, maybe so." Burt muses in reply.

"This is big news," Coop mumbles under his breath. "I gotta tell Kat!"

"Tell Mr. Kat what?" inquires Millie, who had happened up to him at that very moment.

"Well, uhm," Coop stammers as his mind races for a plausible cover story. "Tell him, uh, that is...Look! A monkey!" Coop quickly motions toward the ceiling, upon which Millie quickly gazes up toward it. Breathing a sigh of relief that neither Millie nor his dad had questioned the event, the little boy quickly dashes back up to his room to give Kat the news.

Coop rushes into his room, urgently calling, "Kat! Kat!" Upon hearing him, the space cat pokes his head out of the cat house. "Goodness, what's wrong, lad?"

"I-just-saw-Dennis," Coop puffs. "He-was-on-top of a VOLCANO!"

"Gracious, we haven't a moment to lose," Kat replies with concern as he quickly but carefully climbs down. "The teleporter should be in working order by now." He holds the device out and rotates it in a quick circle, but oddly, no vortex appears.

A perplexed Kat stares at the device. "Hmm, this is strange...perhaps a wire is out of place?" Just then, his gaze falls on the open battery compartment, which is empty. The space cat's purple face turns bright red. "Uhm, pardon me, Coop, but may I...borrow two batteries, please?"

"Absolutely!" Coop obliges, as he opens his desk drawer, removes a small packet of batteries, and hands Kat two of them.

"Thank you, lad." Kat replies, upon which he quickly shakes the teleporter again, causing a vortex to brew up. "Perfect!"

Coop rushes up to the vortex, with Kat following closely behind. "Dennis, can you hear me?" He takes a length of rope out of his pocket, which he then ties into a lasso. "We've come to save you!" The little boy whips the lasso above his head vigorously; unfortunately, the vortex proves to be too strong and ends up drawing him in, with the lasso wrapped around him. "WAAAAAAAAAAUUUUGH!" Kat quickly grabs the other end of the rope in a desperate attempt to save his young owner, but ends up getting drawn in, too. "AAAAAAAAAAHHHHH!"

As the boy and cat swirl through the vortex at top speed, they moments later find themselves deposited over the Appalachian mountains. The two scream in fear as they plummet downward, until someone quickly catches them. "Gotcha!" says a familiar voice, upon which the two look up to see...

"Dennis!" Coop exclaims happily.

"Hi, guys." says Dennis, who's hanging onto a ledge just above them.

"W-we're s-s-so glad you're safe, lad," Kat chatters as he holds his arms around himself for warmth.(This unfortunately was not a very good place for a hairless cat.) "W-we were q-quite worried about y-you."

Noticing the souvenir cap Dennis is wearing, a curious Coop inquires, "So, where ya been, Dennis?"

"Oh, well, sort of here, there, and everywhere." Dennis replies.

"W-w-well, we h-h-have some g-good news," Kat replies. "The teleporter has b-been repaired, and n-now w-we can bring you h-h-home."

An excited look crosses Dennis' face. "Ooh, cool! Thanks!"

Aiming the teleporter just below them, Kat quickly rotates it, causing a huge vortex to form underneath them. Coop turns to Dennis. "Ready, Dennis?"

"Ready!" Dennis replies, upon which he lets go of the ledge, sending the three plummeting toward the vortex. "HERE WE GO-O-OOOOO!" As the swirling pool swallows them up, it deposits the three in a heap in Coop's back yard. "WHOOOOOOOOOOA! OOF!"

"Oof," Kat groans from the top of the stack. "Are you okay, lads?"

"Yes..." Coop moans.

"Momentarily..." Dennis mumbles.
